Carbon 14 dating machine

After the organism dies it stops taking in new carbon.To measure the amount of radiocarbon left in a artifact, scientists burn a small piece to convert it into carbon dioxide gas.In the following section we are going to go more in-depth about carbon dating in order to help you get a better understanding of how it works.

By measuring the ratio of carbon-12 to carbon-14 in the sample and comparing it to the ratio in a living organism, it is possible to determine the age of the artifact.The ratio of carbon-12 to carbon-14 is the same in all living things.However, at the moment of death, the amount of carbon-14 begins to decrease because it is unstable, while the amount of carbon-12 remains constant in the sample.Radiation counters are used to detect the electrons given off by decaying Carbon-14 as it turns into nitrogen.In order to date the artifact, the amount of Carbon-14 is compared to the amount of Carbon-12 (the stable form of carbon) to determine how much radiocarbon has decayed.
